There's a GUI problem on the peers page which also exists for the NXT client.

Using Windows 7 and Chrome as the browser, view the peers page. Move the mouse cursor over one of the peer services shown ("CS" for example) which then shows the balloon (bubble or whatever you want to call it showing the full service name).

When the page refreshes to show updated information, move the mouse off off the service. The balloon remains on the screen.

When changing to other pages now (Dashboard for example) the balloon remains on the screen. If you happen to have a long list of peers and test this with a peer at the bottom of the list, all of the pages now scroll a long ways down showing nothing until you get to the bubble.

So far, the only way I've found to get rid of the bubble is to log out of the wallet.
